Log into the phone system using PCPro. download, and look at 10-12-09. This is your SIP server address. Verify there is an IP address in 84-26 on the same subnet as 10-12-09. This is the DSP resource and this address is what processes the voice packets to the phones.
Verify 10-54 has the license number 5103, and a quantity assigned to the IPPad.
Click on the standard tab, blade config. You want to look at the hardware ports you are using so when you assign an IP phone they don't conflict.
Now once you have hardware port numbers, go to 11-02 and you want to assign your station numbers on a UNEQUIPPED port. I usually start assigning IP stations well above the hardware ports to allow for expansion. There are some limits to licensing where you can place these (max port license)
Now, this is what makes the station an IP station instead of an unequipped port. On the tool bar up top go to programming>Unregistered phones>IP phone list. A small box will appear, scroll to your station number you built and tick the check box, and click ok.
Once you have the station number built assign the name, buttons, DID's, forwarding, and VM as you would normally.
Upload everything you programmed to the system, disconnect, and you are ready to config the phone.
You will go to the phone, and during the boot cycle when the display shows dhcp connecting press hold transfer *# (you should hear tones from the phone when you are doing the key sequence. If not wait and re-try)
The USER is ADMIN password 6633222.
Go to option 2 SIP Settings, Option 2 SIP Server/ URL, 1st server address, and enter the IP address programmed in your system at 10-12-09.
hit ok and back then go to the SIP server port and change to 5080 (default port number). Hit ok, back, back, save etc until the phone exits config mode.
The phone should boot, and connect to the system as an IP Phone.
Let me know how it goes.
